Description
Die Erfindung geht aus von einer Endlosverbindung für Preßbänder bei Rundballenpressen nach dem Oberbegriff des Anspruchs 1, nach dem im wesentlichen eine Über lappung der Bandenden vorgesehen ist, die durch eine flache Druckleiste beaufschlagt werden. Zudem sind solche Preßbänder vorgesehen, die oberhalb und unter halb eines Zugträgers in Form von Gewebeeinlagen eine Deckschicht aus Gummi od. dgl. aufweisen.The invention is based on an endless connection for Press belts for round balers according to the generic term of claim 1, according to which an essentially Lapping of the band ends is provided by a flat pressure bar can be applied. Also are such press belts provided above and below half of a tension member in the form of fabric inlays Have cover layer made of rubber or the like.
Um eine hinderliche Verbindungsstelle auszuschalten und diese auch bei den vergleichsweise dünnwandigen Bändern noch ausreichend und dauerhaft zugfest ausführen zu können, sind aufgrund der Erfindung im Bereich der Über lappungsstelle die einander zugekehrten Deckschichten zumindest teilweise abgetragen, wobei vorzugsweise die Schichtstärke des abgetragenen Teils größer ist als der verbleibende Teil. Darüber hinaus werden die Druckleisten, die sich vorzugsweise über die gesamte Bandbreite erstrecken sollen, so durch Schrauben, Niete od. dgl. angepreßt, daß sie sich nennenswert in die außen gelegenen Deckschichten eindrücken, jedoch können aber auch hier, also außen am Band im Bereich der Über lappungsstelle, Schichten der Deckschichten abgetragen bzw. entfernt sein, um zu erreichen, daß die Druckleisten an der Überlappungsstelle nicht zu weit vorspringen.To switch off an obstructive connection point and this also applies to the comparatively thin-walled belts still have sufficient and durable tensile strength can, are due to the invention in the area of over lapping point the facing outer layers at least partially removed, preferably the layer thickness of the removed part is greater than the remaining part. In addition, the Print bars that are preferably spread over the entire Band width should extend, so by screws, rivets od. Like. pressed that they are worth mentioning in the press in the outer cover layers, but you can but also here, i.e. outside on the belt in the area of the over lapping point, layers of the outer layers removed or be removed to achieve that the pressure bars do not protrude too far at the overlap point.
Weitere Einzelheiten der Erfindung werden anhand der Zeichnung erläutert, in der Ausführungsbeispiele der Erfindung dargestellt sind. Es zeigt Further details of the invention are based on Drawing explained in the embodiments of the Invention are shown. It shows
Fig. 1-3 je eine Überlappungs- und Verbindungsstelle für die Enden eines Preßbandes für Rund ballenpressen für Heu, Stroh oder ähnliches, in landwirtschaftlichen Betrieben anfallendes Gut, und zwar im Längsschnitt. Fig. 1-3 each have an overlap and connection point for the ends of a press belt for round balers for hay, straw or the like, resulting in agricultural holdings, namely in longitudinal section.
Etwa mittig im Preßband 1 befindet sich ein Zugträger als Gewebeeinlage aus einer oder mehreren Gewebeschichten, die sich über die gesamte Länge und Breite des Preßbandes 1 erstrecken; diese Schicht aus den festhaftend in Gummi od. dgl. eingebetteten Gewebeschichten ist mit 2 bezeich net; oberhalb dieser Schicht 2 ist eine Deckschicht 3 aus Gummi od. dgl. und unterhalb der Schicht 2 - an der Band innenseite - ist eine ebenfalls aus Gummi bestehende Deckschicht 4 vorgesehen. Alle Schichten sind dabei durch Vulkanisieren od. dgl. festhaftend verbunden; zudem haben diese drei Schichten im wesentlichen die gleiche Wandstärke von z. B. etwa 2 mm.Approximately in the middle of the press belt 1 there is a tension member as a fabric insert made of one or more fabric layers which extend over the entire length and width of the press belt 1 ; this layer of the firmly adhering rubber or the like. Embedded fabric layers is denoted by 2 ; Above this layer 2 there is a cover layer 3 made of rubber or the like and below the layer 2 - on the inside of the band - a cover layer 4 also made of rubber is provided. All layers are firmly bonded by vulcanization or the like; in addition, these three layers have essentially the same wall thickness of z. B. about 2 mm.
Um eine gute Verbindung der Bandenden 5 herbeiführen zu können, ist eine Überlappung vorgesehen, deren Länge etwa 3-5mal größer ist als die Wandstärke des Preß bandes.In order to bring about a good connection of the band ends 5 , an overlap is provided, the length of which is approximately 3-5 times greater than the wall thickness of the press band.
Um den gehörigen Zusammenhalt der Bandenden 5 sicherzu stellen, werden diese zwischen metallischen Druckleisten 6 gehalten, die somit die Bandenden 5 zusammengepreßt festhalten und sich über die Bandbreite erstrecken. Dazu sind mehrere über die Bandbreite verteilte Niete 7 vorgesehen, die alle Teile an der Überlappungsstelle durchsetzen.In order to ensure the proper cohesion of the band ends 5 , they are held between metallic pressure strips 6 , which thus hold the band ends 5 pressed together and extend over the bandwidth. For this purpose, several rivets 7 are provided which are distributed over the bandwidth and which penetrate all parts at the overlap point.
Gemäß Fig. 1 sind die einander zugekehrten Deckschichten 3/ 4 der beiden Bandenden 5 über die Überlappungslänge hinweg teilweise abgetragen unter Bildung einer Stufe; die Wandstärke W des Preßbandes ist dort auf etwa W/3 bis W/6 reduziert, um so größere elastische Ver formungen im Überlappungsbereich auszuschalten, aber dennoch eine elastische Pressung zwischen den beiden Bandenden 5 zu gewährleisten. Zudem sind auch die außen gelegenen Deckschichten 3, 4 über die Überlappungs länge hinweg im Einflußbereich der Druckleisten 6 in der Wandstärke reduziert, um so die Druckleisten 6 insb. an der Bandinnenseite nicht zu weit vorspringen zu lassen; diesem Ziel dient auch eine feste Pressung der Druckleisten 6, die sich dementsprechend in die Deckschichten 3, 4 eingraben.Referring to FIG. 1, the mutually facing outer layers 3/4 of the two belt ends 5 are plotted on the overlap length away partially to form a step; the wall thickness W of the press belt is reduced there to about W / 3 to W / 6 in order to eliminate larger elastic deformations in the overlap area, but nevertheless to ensure an elastic pressure between the two belt ends 5 . In addition, the outer cover layers 3 , 4 over the overlap length in the area of influence of the pressure bars 6 are reduced in wall thickness so as not to allow the pressure bars 6, in particular on the inside of the tape, to protrude too far; This goal is also served by a firm pressing of the pressure strips 6 , which accordingly dig into the cover layers 3 , 4 .
Gemäß Fig. 2 - hier ist auf eine Darstellung der Druck leisten 6 verzichtet worden - sind die einander zugekehr ten Deckschichten 3, 4 ganz abgetragen worden, aller dings verbleiben auch in diesem Falle noch in der frei gelegten Kontaktfläche 8 kleine Gummiquerschnitte aufgrund der Gummierung der Gewebeschichten. Fig. 2 läßt auch den Abtrag bzw. die Stufen 9 an der Außenseite bzw. in den Deckschichten 3, 4 gut erkennen, wo die Wand stärke auf etwa 1/2 bis 1/3 reduziert wurde. Die Druck leisten 6 finden somit einen ausreichend großen Auf nahmeraum.According to Fig. 2 - here is a representation of the pressure 6 have been omitted - the mutually facing th cover layers 3 , 4 have been completely removed, but remain in this case still in the exposed contact area 8 small rubber sections due to the rubber coating Layers of fabric. Fig. 2 also shows the removal or the steps 9 on the outside or in the cover layers 3 , 4 where the wall thickness has been reduced to about 1/2 to 1/3. The pressure bars 6 thus find a sufficiently large recording room.
Bei der Ausführung gemäß Fig. 3, in der die Druckleisten 6 gestrichelt angedeutet sind, sind im Überlappungsbereich innen bei dem rechts gelegenen Bandende 5 die Deck schicht 4 ganz abgetragen und bei dem links gelegenen Bandende 5 die Deckschicht 3 teilweise im Sinne von Fig. 1 abgetragen worden. Auch hier sind wiederum Stu fen 9 für die Druckleisten 6 angebracht.In the embodiment according to FIG. 3, in which the pressure strips 6 are indicated by dashed lines, the cover layer 4 is completely removed in the overlap region on the inside at the right-hand end 5 of the tape 5 and the cover layer 3 partially on the left-hand end 5 in the sense of FIG. 1 been removed. Here, too, stages 9 for the pressure strips 6 are in turn attached.
Bei der erfindungsgemäßen Verbindungsstelle werden die einander zugekehrten Flächen derart zusammengehalten und verpreßt, daß dauerhaft nahezu alle durch die Gewebeeinlagen aufnehmbaren Kräfte auch über die Ver bindungsstelle übertragen werden können.At the connection point according to the invention the facing surfaces held together in this way and squeezes that permanently almost all through the Tissue deposits absorbable forces also via the ver binding agency can be transferred.
